Introduction to PostgreSQL
PostgreSQL is a free and open source object-relational database management system (RDBMS) that is state-of-the-art, highly scalable, and standards-compliant. It is designed to handle a wide range of workloads, from personal computers to data warehouses or multi-user Web services.
PostgreSQL was developed based on POSTGRES 4.2 at the University of California, Berkeley Computer Science Department.
PostgreSQL was designed to run on UNIX-like platforms. However, PostgreSQL was later adapted to run on a variety of platforms, including Mac OS X, Solaris, and Windows.
PostgreSQL is free and open source software. The source code of the software is available under the PostgreSQL license, a free open source license. This means you are free to use, modify, and distribute PostgreSQL in any way.
PostgreSQL does not require much maintenance because it is highly stable. Therefore, if you develop applications based on PostgreSQL, the cost of ownership will be lower than other database management systems.
